https://connect.hyland.com/t5/alfresco-forum/oncontentupdate-behaviour-throws-internal-error/m-p/124475#M34027 <P>Hi, I'm developing my own extension of Alfresco Community Service using the platform jar. I defined a custom behaviour for the `onContentUpdate` policy that does some logic whenever a node is updated (I need to make it work whenever I update it through a API request, the PUT /node{nodeId}/content using binary data) returning a boolean value. If that boolean is true, the method throws a `PermissionDeniedException`.</P><P>The problem is that, for some reason, this exception I throw is always wrapped on a 500 exception, thrown by the `ContentServiceImpl` class; to be precise, it is thrown a ContentIoException with the phrase `Failed to set content property on stream closure: ...`.&nbsp;</P><P>I don't understand what's going on here. It's like the property gets updated even if I don't want to. What could the problem be?</P><P>Thank you in advance!</P> Mon, 23 May 2022 13:39:40 GMT fsanna 2022-05-23T13:39:40Z https://connect.hyland.com/t5/alfresco-forum/oncontentupdate-behaviour-throws-internal-error/m-p/124475#M34027 <P>Hi, I'm developing my own extension of Alfresco Community Service using the platform jar.
